Abstract
The aim of this work is conducting theoretical and experimental research of the processes and modes of high-temperature processing of steel slags for more complete extraction of the metal component. "FactSage" software complex (version 6.4) was used to execute the thermodynamic modeling of the processes occurring during the recovery of metals from steelmaking slags. The experimental research included experiments on solid-phase and liquid-phase recovery of slag samples at the temperatures of 1000 – 1500 °C. The results of thermodynamic modeling and experimental high-temperature slag processing allows speaking about the advisability of preliminary solid-phase recovery slag in the atmosphere of carbon monoxide with subsequent high-temperature (liquid phase) recovery to obtain separate metal fractions.
